and placed in the-smaller outlet end ofthe 1 tube 5 is a .frail or readilyde'structableplug 9`0f, paper or the like.

When `the tube 5 is filled vwithpowderI as indicated .in Figure 3, .and the capsy and7 arein place upon the ends of the tube, itis evident that the charger may. be readily handled with safety andwitlioutdanger` of spilling thepowder. .Whenjit is ,de siredtot charge the ldrill hole,' the cap ,7 is removed from the outlet end of the tube 5, "whereupon the latter is inserted in thedrill hole with the smaller voutlet lend: foremost, the

readily destructable plug 19 preventing spill-l ing of the vpowder after removal of the cap 7. However, upon-insertion of the tube 5 completely into the drill hole, the plug 9 will become destroyed through Contact with obstructions or projections or by exeessive'vibration of the charge containing tube 5 so that upon removing thelatter from the drill 11016 the'pOWdGI will pour out ofthe tube 5 Y into the drill hole. However, when found necessary under extraordinary conditions, the dispensing of the powder from the tube 5 may b e effected in 4any suitablemann'er upon removal of the cap 6 although the latter' is not usually necessary and the charging operation is accordingly V.usually possible with extreme vsafety'or without danger of spilling the powder. or igniting the same in? advertently. In lowering the tube into the drill hole a rope or cord is attached to the loop 8 of the cap 6, it being understood that the vcap fits the tube tightly enough to pre- -vent the cap from being displaced by the weight of the filled tube; to remove'the cap will of course, require forcible manipulation.

In order to permit lling. of the tube 5 conveniently and safely without danger of igniting thepowder or spillingthe same, I provide a sleeve 10 adapted to slide on the inlet or larger endof the tube 5 withla fricinto a guideway 12 when thetube 5is moved.
